Angular attributes are one of the key characteristics of the Angular framework. They are used to extend HTML with custom elements and behaviors, essentially enabling developers to create their own HTML elements.
Angular elements are self-bootstrapping. This means they automatically bootstrap themselves when they are added to the DOM. The main purpose of Angular elements is to provide a bridge between the Angular framework and any HTML-based UI.
Let's consider an example scenario. Suppose a developer is building a tool for online surveys. While the majority of the app is built using Angular, there could be a requirement to generate a custom element, let's say, a unique type of form input or a one-of-a-kind voting mechanism.
In such cases, an Angular element could be the perfect solution. It could create an entirely new HTML element, say <survey-input>
, which may contain complex logic and interactions but could be used just as a normal form input. This type of novel HTML element wouldn't interfere with the wider app and could even be reusable in different parts of the application or even in other applications.
One point to remember is that while Angular elements can extend HTML, they don't directly manipulate the Document Object Model (DOM). Angular operates under the "you don't touch the DOM, I don't touch the DOM" premise. All the DOM manipulation tasks are handled by special Angular methods, which are independent of the actual rendering process.
Lastly, Angular elements are not primarily intended for server-side rendering. Although Angular does offer tools for server-side rendering (Angular Universal), the main focus of Angular elements is to augment and enhance the client-side user interface.
In conclusion, Angular elements can significantly impact the way user interfaces are designed, leading to more intuitive, interactive, and user-friendly applications. Being able to create custom HTML elements that carry with them their own styles, behaviors, and interactions is a powerful tool that every web developer can benefit from.
